SCI1920A HD SWIR ROIC (Analog Out)

Attollo’s SCI1920A Readout Integrated Circuit (ROIC) is designed for SWIR focal plane arrays with a resolution of 1920 x 1080 pixels with a pitch of 15 microns. The small pixel pitch enables high-resolution imaging in a small form factor camera.

The SCI1920A ROIC pixels use a Capacitive Transimpedance Amplifier (CTIA) and can support readout of P on N or N on P photodiodes. Snapshot shutter exposure time control with integrate then read (ITR) or integrate while read (IWR) is supported. In ITR mode the pixel can be read out using Correlated Double Sampling (CDS) to achieve the best noise performance.

The ROIC is well-suited for SWIR applications using detector materials such as InGaAs and CQDs.  Attollo can deposit customized metallization stacks for your application.

Available for purchase in full, half, and quarter wafers.
